While details about just how much of the band's back catalog are still to be revealed, the partnership will kick off on July 7th with three downloadable tracks from the bands new album are made available for Rock Band and Rock Band 2. The three tracks from 21st Century Breakdown include "21 Guns," "Know Your Enemy," and "East Jesus Nowhere."

While maybe not "a whole Green Day Rock Band" as singer/guitarist Billie Joe Armstrong hinted at during a radio interview this week, MTV Games notes that "additional Green Day songs and projects will be announced at a later date."

Any requests? Besides the obvious option of being able to play "Longview" in LEGO Rock Band, that is.
